Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or outdated likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:

  • Odd noises when the system turns on
  • Frequent breakdowns and need for repairs
  • Refrigerant leaks
  • Temperature control issues or thermostat malfunctions
  • Rust, corrosion, or cracking
  • Uneven heating/cooling or poor air circulation
  • Unusually high energy bills
  • An HVAC system that's over 15 years old

If you notice any of these HVAC issues, you should have a technician inspect your system. A local professional can diagnose problems and determine whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Chelmsford

What you spend on HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:

  • Split or mini-split: If your home lacks the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of indoor units that control the temperature in individual rooms. These interior units are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of having the capability to use either electricity or gas for power.
  • Heat pump: Heat pumps exchange warm and cold air between your home and outside. They don't produce their own heat or AC, so they function best in mild climates.
  • Packaged heating and air: Packaged HVAC systems are a practical choice for smaller houses. These systems have a single heating and cooling unit, normally located in an attic or basement. They're small, energy-efficient, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complicated and may need multiple types of maintenance. Prices for common jobs are as follows:

HVAC Unit TypeCost
Split$2,072-$5,282
Hybrid Split$4,198-$7,734
Heat Pump$3,251-$33,122
Packaged Heating and Air$272-$453

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
  • Keep your system clean. Cleaning your condenser fan blades, grills, indoor evaporator coil, and ductwork regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
  • Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the frequency with which you need to run your HVAC.
ServiceCost
Filter Replacement$68-$181
Condensor Cleaning$1,360-$4,080
Thermostat Repair$91-$227
Ductwork Cleaning$435-$1,088

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Explain your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled by the state.

Massachusetts doesn't have state-level licensing requirements for HVAC contractors. However, HVAC technicians who do certain cooling work may need a Refrigeration Technician License for larger projects.

It's also a good idea to check with your city or municipal government to learn if HVAC contractors have any local licensing requirements. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

It’s important to know what the work process is going to look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC system, ask your installation company to provide details on the new features, estimated installation time, energy efficiency, brand, and model. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Reputable HVAC companies back their services with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Get written bids before starting HVAC work. The quote should cover costs for both labor and materials. Review all terms carefully before signing.

Frequently Asked Questions About HVAC in Chelmsford, MA

You should have your HVAC system inspected approximately twice yearly. After completing their inspection, your technician will inform you what services are required. You should also have your system inspected if you start noticing issues such as unusual smells, strange noises, or leaks. If your system has ductwork, you should have it inspected every few years.

Normally, it's a good idea to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it typically sees the most use.

You can save energy throughout the year by making it easier for your HVAC system to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as possible, and avoid making drastic changes — adjust it only a few degrees at a time. You may also consider a smart thermostat.

It takes roughly one to three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take anywhere from a few hours up to two days. This timeline will be determined by the size of your home, the accessibility of your system, and any new issues your technician uncovers.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will generally be more effective than window units for cooling.

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

Your HVAC company may offer financing options via a third-party lender, or you may choose to obtain your own loan. It's a good idea to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and change or clean your air filters on a regular basis.
  • Schedule regular inspections to take care of issues as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as you can.
  • When replacing part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
